I just sent an email to their customer service 10 mins ago. Their website says version four works with the HTC ONE, but didn't see any version 4 or one updated today.
Also not sure how I would feel about it if it's $50.
While the S4 has a better UI it's not as responsive as the One. I already had to delete and set up my S4. Either the TV (Samsung) and/or the Receiver (Denon) won't turn on.
Touchsquid again emailed me to let me know that the "Home" app will be updated today. The "Home" version allows less remotes (I believe 4) programmed to the app and does not have macros. This version is $20. They allow you to upgrade to the "Pro" version from the "Home" versionwith an app for an extra $30.
The reason I am contemplating the "Home" version now is pretty much for the use of the DirecTV 4 colored buttons which the HTC ONE base app doesnt have. I wonder if HTC/Peel is planning an update with macro capability or the ability to add custom buttons.
